CTEK D250S Dual
12V 20A Battery to Battery Charger

The D250S DUAL charger takes power from DC sources such as alternators, solar panels or wind turbines and optimises this power to meet the charging requirements of different battery banks. The D250S DUAL automatically selects the best connected DC energy source for the purpose and switches between these energy sources to achieve high efficiency multi-stage charging. The D250S DUAL is particularly suitable for charging vehicles that do not have access to grid power supplies. Charging automatically starts as soon as DC energy is provided to the charger, for example from alternators when a vehicle is started or from solar panels when connected.

The D250S DUAL ensures your batteries are always in good condition and help prolong their lifespan.
